How to convert degrees Fahrenheit to degrees Celsius

Formula: °C = (°F − 32) × 5/9. Worked example: 68 °F = 20 °C. Quick estimate: subtract 30 and halve (68 °F → 19 °C, exact 20 °C). Good enough for weather, not for cooking or fever.

About these units

The Celsius and Fahrenheit scales meet only at −40°. Water freezes at 0 °C = 32 °F and boils at 100 °C = 212 °F, so one Fahrenheit degree is 1/1.8 of a Celsius degree. Fahrenheit is used in the US for weather, body temperature and oven settings (350 °F ≈ 177 °C).
